Prepping New Wood For TWP Stains

TWP Stain Tips for New Wood Decks

Preparing New Wood for TWP Stains

When applying TWP Wood Stains to new wood for the first time, following the correct preparation steps is crucial. New smooth wood or decking is not ready for staining before installation or immediately after. Always adhere to the TWP Wood Stain guidelines rather than relying on advice from a lumber yard or paint store, as they may not fully understand the prep requirements for optimal results.

TWP and New Smooth Decking or Exterior Wood

New smooth wood is not sufficiently absorbent for TWP Stains due to higher moisture content and the presence of “mill glaze.” Mill glaze is a waxy film that forms during the milling process when high-speed blades heat the wood, drawing out sap and moisture. As this cools and dries, it creates a coating that prevents TWP Stain from properly penetrating the wood grain.

Important Note:

New Rough Sawn Wood/Fencing: Unlike smooth wood, new rough sawn vertical wood or fencing can be stained immediately after installation without waiting or extensive preparation, as it lacks mill glaze and is highly absorbent.
Ensure the rough sawn wood is fully dry before staining. If it has aged or oxidized (turned gray), prep it using the Gemini Restore Kit before application. For newly installed rough sawn wood, one coat of stain is usually sufficient.

Proper preparation ensures your TWP stain delivers its intended durability and beauty, whether you’re working with smooth or rough sawn wood.

TWP Stains and Moisture Content

Moisture Content of Wood When Applying TWP

Whether the wood you are staining is new or more aged, the moisture content is an important factor in the timing of stain application. Applying TWP or most any wood stain for that matter to a wood surface that is still holding too much moisture can result in many problematic issues. Trapping moisture in wood can promote the growth of mold and mildew. A moist and mildew infected environment can lead to wood decay and rot. This should be avoided at all costs. Wood rot will most likely progress to structural damage causing expensive repairs and replacements.

After the wood surface has been cleaned and prepped correctly prior to staining, it should be allowed to air dry for several days depending on the age, condition, and porosity of the wood. A good rule of thumb is to let the surface dry for several days before staining and do not stain if rain is expected. A deck that is mostly shaded may take a day or two longer to dry than a deck that sits in full sun all day. Weather and climate can also be a factor.
